ANTISKIDDING DEVICE FOR VEHICLE-WHEELS.

ATo all whom 'it may concern Be it known that I, HARRY D. Wann, former a resident of Canastota and now a Antiskidding Devices for Vehicle-Wheels,

\ of which.the followin is a. specification, taken in connection wit the accompanying drawings, which form a part of the same.

This application is based upon and is a division of my co-pending application Serial No. 402,778, tiled November 12, 1907.

This invention relates to certain improvements in anti-skidding` devices for vehicle wheels having multiple tires, and is par` ticularly adapted `for use in connection with dual tires with which the wheels, and espe cially the' traction wheels, otinany self-propelled vehicles are now equipped.

These tires are usuall madef solid rubber and are secured si e by side some distance apart transversely upon the periphery of the rim orfelly of the wheel leaving an annularspace between the -adjacent faces of the tires.

i My main object is to, provide a simple, practical and eilicient grip-tread which may e easily and quickly applied to or removed eriphery of both tires simultaneously, and) held in` place bylvattaching ele. ments, withinthe Wearin surfacesV of the grip ing elements. ,In ot er words, Iha've soug t to .utilize the annular space between the 'tires for the reception of the vattaching elements as well as portions ofthe gripping elements, which are depressed into sai space. y

-Another object is to provide means also,

from the located within' the annular groove or space between the tires, for taking up the slack i n of the grip-tread.

A further object is to make'theg` attaching elements located' withinthe aimular space separate from the tires so th 't the entirer- Vgri `tread may be free to shi t'yfcircumferentlally relatively to the tires, and still berguided or held in operative position against transverse displacement by theportions of Vthe gripping elements which may in :[slilch` annular space.

be located 'specification orte-ttm raten.

.a vehicle wheel comprisin the mamma@ drawings. shaving fin Patented J an. 8', 1918.

a somewhat diagrammatic way an illustrative example of m invention,

Figure 1 is a si ev elevation partly in section showing a form of the improved antiskidding -device applied to a dual tire vehicle Wheel.

F ig. 2 is a` top plan view of a portion of thewheel and device; and

Fig. 3 is a transverse sectional lview thereof.

In all of these several views, I have shown a rim 1, upon whichis mounted a air o solid rubber, or elastic tires 2 spaced) teivening annular groove 3, the tires 2 being separate andv preferably seated in separate channel rings 4 forming a part of the main` rim 1, although in s ome instances, these tires 2 may be united at the bases of ltheir meeting edges by a comparatively thin webv fof the same material.

These dual tires are of the same diameter andl their peripheries are preferably at transversely, and while they serve, in a measure, to prevent skidding of the wheels on dirt pavements, they are nevertheless susceptible to the same sliding or skidding dif-4 iculties as are experienced in the use. of ingle pneumatic tires, and in order to overcome this liability I have provided separately constructed -an-ti-skidding devices o rl griptreads, consisting in the form illustrated of' a plurality, in this instance, two circular. series of wearing plates or sheet metal tread apart forming an inmembers 24, one series for each of the tires the other series and their attaching ends a are depressed withintheir wearing surfaces -so` that the attaching elements 26 and 27 are located within said wearing surfaces.

The inper depressed ends of the plates of. each series"are located within the annular grooves'or recesses 3 between the tires, as best seen in Fig; 3, and the circular attachingelemmt 27 located wasmand.

groove or space, and usually consists of a chain hai-'ing its links attached to the 1nwardly depressed hook-shaped attaching.

held by the circular chains E26, preferablyV loosely engaging with or held in alineinent by the sides of the wheel rim so as to assist iii this way in maintaining the lateral alinenient of the grip on the tire. Suitable connecting links 29 may as illustrated be used to connect the outer attaching hooks 25 to lthe side chains 26 and it is desirable to form the tread members 24 with substantially flat tread portions in engagement with the tire tread and with inwardly projecting angular securing flanges or portions 28 flaring out away from the sides of the tire as illustrated so as to minimize cutting or wear thereon. The chains or attaching members may have their ends adjustably secured by any suitable securing device such as the special link and adjusting nut 9 shown in Fig. l.

Many other modifications or different forms of the gripping elements and attachingie'leinents tliereforcrnay be used, the 1nveiition not being of4 course limited to the particular forms, arrangements orA propertions illustrated or described, since what is claimed is:

1. In combinationwith the rim of a vehicle Wheel and an elastic tire having multiple treads spaced apart to form an intervening annular groove and having substantially ilat tread faces, of an anti-skidding device coinprising two staggered series of sheet metal tread members in the forni of substantially rectangular lgripping plates having substan- I tially [lat portions to engage the flat tire treads and having inwardly projecting angularly arranged securing :ges tiaring out away from the sides of thev tire to minimize cutting or Wear thereon, and integi'al attaching hooks on said plates depressed within the Wearing portion of the tread members, a chain attaching member located in the ann-ular groove between the tire treads and selocated within said groove and outer chain attaching members connected to said outer l"tt'taching hooks and located substantially opposite the wheel rim to assist in alining rstiid gripping plates.

2. In combination with the rim of a vehicle wheel and an elastic tire having multiplo tread faces, of an anti-skidding device comprising two series of metal tread members in the form of gripping plates having substantially flat portions to engage the flat tire treads and having imvardly projecting angularly arranged securing flanges flaring out away from the sides ot' the tire to minimize cutting or wear thereon, and integral attaching hooks on said plates depressed within the wearing portion of the tread members, a chain attaching member located in the Vannular groove between the tirc treads and secured to the central series of attachinghoolts located within said groove and outer chain attaching members connected to said outer attaching hooks.

3. Iii combination with the rim of a -vehicle wheel and an elastic tire having multiple treads spaced apart to torni an intervening annular groove and having substantially flat tread faces, of an anti-skidding device comprising two staggered series of 'sheet metal tread members forming gripping plates having substantially tlat portions to engage the flat tire treads'and having inwardly projecting an'giilarly arranged securing flanges ,tlaring out away from the sides of the tire., and integral 'attaching portions on said plates depressed within the wearing portion of' the tread members, a chain attaching member located in the annular groove between tlie tire treads and secured to the central series of attaching portions located within said groove and outer chain attaching members connected to said outcrattaching portions and located substantially opposite the wheel rim to assist in` alinng said gripping plates.
